Why?
Because 80,000 fans who tailgate in a parking lot overlooking the New Jersey Turnpike and a never-ending construction site, enduring rain, sleet, and failing escalators, never gave up confidence that the season would improve when it started 0-2 and nearly became 0-3.
Because perfection eventually ends, and when it does, we tend to remember the how and when more than we should. Perfection is one of those "none more black" states; it can't be one-upped, only lessened. A perfect ending is one you don't guess 19 weeks early, and it includes drama, hard work, and competitiveness.
Because this is the first championship won by a New York sports team since 2000 (yes, the Devils won the Stanley Cup in 2003, but I'm being geographically specific: that side of Lincoln Tunnel). When I was being snarky about donuts, I surmised a reversal of fortune for the Yankees, as they were the last to hoist a big pile of metal in victory. Right turn, wrong sport. But I'm not complaining.
No Red Sox-Patriots-Celtics sweep this set of seasons. 2007 is over and done; I'm thinking that the Devils and either Yankees or Mets should join the Giants in celebrating 2008. That would be a perfect ending.
